How do you count carbons on cycloalkanes?
Around the ring, starting at whichever carbon gives you the smallest numbers in the final name.
Suppose we have a cycloalkane ring with five carbon atoms and two methyl groups attached. These two methyl groups could be adjacent on the ring, in which case we would number the carbons to give the name 1,2-dimethylcyclopentane; alternatively, there could be one space between the two methyl groups, giving rise to the name 1,3-dimethylcyclopentane. These are the only options available to us; if we had 1,4-dimethylcyclopentane, we would have simply numbered the ring the wrong way around. Numbering in the opposite direction would demonstrate that this was actually 1,3-dimethylcyclopentane.

To count carbons on cycloalkanes, start by identifying the number of carbons in the ring. Then, add any substituent carbons attached to the ring.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
